bigdaddy Posted August 13, 2003 Posted August 13, 2003 I have a 1972 Simplicity with the 16hp briggs engine. Every time I try to start the beast it backfires once or twice and then starts. Any comments?
UCD Posted August 13, 2003 Posted August 13, 2003 Its just coughing to clear it self. Give it some Cough syrup!!!
srwven Posted August 13, 2003 Posted August 13, 2003 First thing I would look at is the carb. Check the float bowl and choke. Clean it out and then adjust it. From there, your points and armature.
Agricola Posted August 13, 2003 Posted August 13, 2003 I wonder if there is a small timing problem that manifests itself only when you first start the machine. Like an advance that doesn't retard as it should. Maybe the Briggs site has an answer. See my post on Briggs manuals
MPH Posted August 13, 2003 Posted August 13, 2003 Might be as simple as the plug. My B112, which uses more then a bit of oil, gets to actting like the carb is wacked out again, spittin' and sputterin' and generally running like-----, remove plug, clean it, and she starts and purrs like it should...MPH
pofarm Posted August 14, 2003 Posted August 14, 2003 You might also check the flywheel shear key. I have a push mower that did the same thing. It finally got so bad that it would jerk the rope out of my hand when I tried to start it, but it still ran. I checked the key and it was sheared so bad that I don't know how it ran at all.
patrician12 Posted August 16, 2003 Posted August 16, 2003 These engines suck so much gas when choked because the carbs are enormous and they tend to bleed.Would you believe gas collects in the muffler and ignites.Unscrew your muffler like I did and see if the backfire goes away.
